First Raspberry Pi Zero Hack – Piggy-Back WiFi.
And we have the first Raspberry Pi Zero hack! In less than 72 hours from the official release announcement [Shintaro] attached an Edimax WiFi USB Adapter directly to the USB solder pads on the Pi Zero. He couldn’t bear to disturb the small dimensions of the Pi Zero by using the USB On-the-Go (OTG). The OTG is needed to convert the micro-USB connector on the board to a full USB-A connector.
The case was removed from the Edimax and the device and Zero wrapped in Kapton to insulate the exposed solder points. Power was taken from the PP1 and PP6 …read more
The Internet of Reflow Ovens
Using a toaster oven to reflow solder isn’t a new idea. But [Sukasa] wanted something that had more features and improved appearace. So he married a Netduino, a toaster oven, and some solid state relays to made a clean-looking reflow oven. His goal was to have nothing look like an overt modification to a casual observer. Inside, however, the oven now has a network connection for system status via a Web browser or JSON.
The new brains of the oven are a Netduino Plus 2 and an I2C port expander that connects to a few extra I/O devices. The challenging …read more
Thorough Macbook Charger Teardown Reveals Some Complex Circuitry
Apple has a reputation in the tech world as being overpriced, and nowhere is that perception more common than in the Hackaday comments. The standard argument, of course, is that for a device with equivalent specs, Apple charges a lot more than its competitors. That argument is not without its flaws, especially when you consider factors other than simple specs like RAM and processor speed, and take into account materials used and build quality. But, as this teardown by [Ken Shirriff] shows, Apple’s attention to detail extends beyond simply machining Macbook bodies out of aluminum.
In his teardown, [Ken Shirriff] …read more
Fail of the Week: Dave Jones and the Case of the Terrible Tablet
Nothing spices up a quiet afternoon like the righteous indignance of an upset engineer, especially if that engineer is none other than [Dave Jones], on his EEVblog YouTube Channel. This week [Dave] has good reason to be upset. A viewer sent him what looked to be a nondescript 2010 era tablet from a company called Esinomed. From the outside it looked like a standard issue medical device. Opening up the back panel tells a completely different story though. This thing is quite possibly the worst hack job [Dave] (and we) have ever seen. This is obviously some kind of sales …read more
The $5 Raspberry Pi Zero
Rumors about a new Raspberry Pi have been circulating around the Internet for the past week or so. Speculation has ranged from an upgraded Model A or compute module to a monster board with Gigabit Ethernet, USB 3.0, SATA and a CPU that isn’t even in production yet. The time is now, and the real news is even more interesting: it’s a $5 Raspberry Pi Zero. It’s the smallest Pi yet, while still keeping the core experience. …read more
